Granular Activated Carbon
Three lab-verified iodine grades, screened to mesh 4x8, 6x12 and 8x30. Every grade below links to its full Sucofindo specification — real figures, not marketing copy.
Our Grades
Pick a grade, or tell us your spec
The three grades below are what we run regularly, each backed by its own independent laboratory report. If your process needs an iodine number in between, we produce to order.
Granular Activated Carbon — Iodine >1000
1,137.27mg/g iodine, lab-testedHigh-grade carbon for demanding purification, tested at 1,137.27 mg/g iodine.
Granular Activated Carbon — Iodine <1000
929.27mg/g iodine, lab-testedA cost-efficient working grade for everyday filtration, tested at 929.27 mg/g iodine.

Mesh Sizes
Three granule fractions
Every iodine grade is available in all three fractions — choose by flow rate and contact time, not by grade.
4x8
Coarse
Largest granule. Low pressure drop — suited to high-flow filter beds.
6x12
Medium
The general-purpose fraction, balancing contact time against flow resistance.
8x30
Fine
Highest surface area per bed volume for demanding adsorption duty.
Applications
Where our carbon does its work
Water purification
Removing colour, odour, chlorine and dissolved organics from drinking water, process water and wastewater streams.
Metal capture
Adsorbing dissolved metals from industrial process liquids — one of the two applications our carbon is produced for.
Industrial filtration
General-purpose adsorption duty where high pure-carbon content and a clean, dust-free granule matter.
